Embodiment 1

[0020] The present invention is a kind of production technology of vicuña cashmere double-sided smooth wool, comprising following process steps:

[0021] S1: Prepare raw materials for camel hair double-faced smooth wool, including 50% camel hair fiber by weight, 25% Australian wool top fiber with a quality count of 66S and 25% Australian wool top fiber with a quality count of 70S;

[0022] S2: The dyed or undyed camel hair fiber is made into 14 / 1 male slub yarn through wool blending, carding, mule spinning and automatic winding processes; the dyed or undyed quality count is 66S Australian wool top fiber and Australian wool top fiber with a quality count of 70S are made into 14 / 1 public count slub yarn through blending, carding, mule spinning and automatic winding processes; the relative humidity is controlled at 50% in the spinning process ~65%, temperature 25℃~30℃;

[0023] S3: Warping the yarn obtained in S2, wherein the slub yarn made of camel hair fiber with a count of 14...

Embodiment 2

[0029] The only difference from Example 1 is that a softening process is also provided between the thorn fruit process and the drying process in the S4 step, and 4% silicone softener and 6% finishing are added to water at 40°C ± 5°C. The soft mixed liquid is made with 6% smoothing agent and the pH value is adjusted to 5-6, and the cloth after the thorn fruit process is immersed in the soft mixed liquid for 35 minutes. After the S4 step, the chitosan finishing solution is applied to one side of the inner layer fabric, the weight percent of chitosan in the chitosan finishing solution is 5%, the weight percent of amino acid sulfate ionic liquid is 4.5%, epoxy The weight percent of the plasticizer is 0.225%. The epoxy plasticizer is a mixture of epoxy butyl oleate, epoxy octyl oleate and epoxy decyl oleate. The chitosan finishing solution also contains a chitosan cross-linking agent, and its weight percentage in the chitosan finishing solution is 0.1%. The chitosan crosslinking ...

Embodiment 3

[0031] The only difference from Example 1 is that there is also a softening process between the thorn fruit process and the drying process in the S4 step, and 3% silicone softener, 5.5% finishing agent and 5.5% are added to water at 40 ° C. % smoothing agent to make a soft mixed solution, adjust the pH value to 5-6, and immerse the cloth after the thorn fruit process in the soft mixed solution for 30 minutes. After the S4 step, the chitosan finishing solution is applied to one side of the inner layer fabric, and the weight percent of chitosan in the chitosan finishing solution is 3.5%, the weight percent of amino acid sulfate ionic liquid is 3.5%, epoxy The weight percentage of plasticizer is 0.15%. The epoxy plasticizer is epoxy octyl oleate. The chitosan finishing liquid also contains a chitosan cross-linking agent, and its weight percentage in the chitosan finishing liquid is 0.06%. The chitosan crosslinking agent is a mixture of formaldehyde and acetic anhydride, and the...

Abstract

The invention discloses a production process for vicugna double-faced woolen fleece. The production process for the vicugna double-faced woolen fleece comprises the following process steps: preparingthe following raw materials of the vicugna double-faced woolen fleece in percentages by weight: 50% of camel hair cloth fibers, 25% of Australian wool top fibers with the quality number being 66S and25% of Australian wool top fibers with the quality number being 70S; preparing dyed or non-dyed camel hair cloth fibers into coarse yarns with the metric count being 14/1 by willey, carding, mule spinning and an automatic spooling process; preparing the dyed or non-dyed Australian wool top fibers with the quality number being 66S and the dyed or non-dyed Australian wool top fibers with the qualitynumber being 70S into coarse yarns with the metric count being 14/1 by willey, carding, mule spinning and an automatic spooling process; carrying out warping on the obtained yarns; weaving the spun yarns on a rapier loom by a single-warp and single-weft mode; and successively carrying out hemming, fulling, scouring of wool fabric, dewatering, drying, decatizing, fuzzing, burring, drying, scaldingscissoring and decatizing processes on the woven cloth to obtain the finished product. The double-faced woolen fleece feels soft, and is high in heat-insulation property.

Description

technical field [0001] The invention relates to a production process of vicuna double-faced smooth wool. Background technique [0002] With the improvement of people's living standards, the requirements for the wearability and decoration of clothing are getting higher and higher. Cashmere wool and other high-grade raw materials are more and more used in the production of textiles and cloth, and camel hair fiber is hollow bamboo The nodular structure is more conducive to keeping warm and cold, and is one of the important raw materials for making high-grade woolen textiles. Camel hair products are characterized by lightness, softness and warmth. They are called "natural protein fiber" and "soft gold" by fiber experts because of their softness, lightness and rarity. The finished product is still not seen, mainly because of the special nature of camel hair fiber, and the poor setting of parameters in the weaving and weaving process will lead to a lot of waste of raw materials. ...
